Ard Biesheuvel 12a37b2ae1 MdePkg/BaseMemoryLib*: check for zero length in ZeroMem ()
Unlike other string functions in this library, ZeroMem () does not
return early when the length of the input buffer is 0. So add the
same to ZeroMem () as well, for all implementations of BaseMemoryLib
living under MdePkg/

This fixes an issue with the ARM implementation of BaseMemoryLibOPtDxe,
whose InternalMemZeroMem code does not expect a length of 0, and always
writes at least a single byte.

myronporter 2fc59a003e Minor grammatical work--mostly adding periods. Items with ONLY period added did not have the heading date changed, but Items with content changes had heading copyright dates updated. Sending separately a list of files missing Doxygen @param and @return information. (PENDING)

qhuang8 1fef058f4b clean up all of eight BaseMemoryLib instances in MdePkg with the following updates:
1.	Remove .intel_syntax directives in GCC assembly files. All these assembly files have been updated to use the preferred syntax for GAS
2.	Correct the incorrect comments for internal worker functions for SetMemXX() and ScanMemXX(). The Length parameter is actually the counter of 16-bit, 32-bit or 64-bit value. 
3.	Simplify the logic in ZeroMemoryWrapper.c for BaseMemoryLibOptPei instance to remove the conditional statement for zero length. This logic is already covered by worker function InternalMemZeroMem(). 
4.	Cleanup all the Wrapper C files in BaseMemoryLib instances. They are supposed to be shared by all these 8 BaseMemoryLib instances, but are out-of-sync after some maintenance. This patch re-syncs them and makes them exactly the same.
5.	Cleanup MemLibInternal.h so that it is shared by 6 BaseMemoryLib instance except for PeiMemoryLib and UefiMemoryLib.

lgao4 2bfb60098f 1. Change 0 == Length style to Length == 0
2. Clean BasePeCoff library instance, only keep one copy PeCoffLoaderEx.c file for IA32, X64 and IPF arch
3. Clean the confused comments
